Question 33139: I HAVE A FEW QUESTION ON HOW TO DO THINGS
1. 82.1 G = ?KG
2. 12 SQ MM = ? SQ CM
3.4 CU M = ? CU DM
4.WHAT IS THE PERIMETER OF A SQUARE WHOSE SIDES MEASURE 26 CM
5. PERMITER OF A RECTANGLE 41 M LONG AND 17 M WIDE
6.FIND THE CIRCUMFERENCE OF A CIRCLE WHOSE RADIUS IS 80FT

Answer by sarah_adam(201) (Show Source): You can put this solution on YOUR website!
a) 1 kg = 1000 g
1 g = 1/1000 kg
82.1 g = 82.1/1000 = 0.0821 kg
b)12 SQ MM = ? SQ CM
1 sqmm = 100 sq cm
12 sq mm = 12/100 sq cm = 0.12 sq cm
c)4 CU M = ? CU DM
1000 cu. decimeters = 1 cu. meter
4 CuM= 4000 Cu DM
d)WHAT IS THE PERIMETER OF A SQUARE WHOSE SIDES MEASURE 26 CM
Perimeter of square = 4S
where S = side of square = 26cm
Perimeter = 4(26)= 104 cm
e)PERMITER OF A RECTANGLE 41 M LONG AND 17 M WIDE
Perimeter of Rectangle : 2(L+W)
P = 2(41+17)=116 M
f)FIND THE CIRCUMFERENCE OF A CIRCLE WHOSE RADIUS IS 80FT
Circumference of circle = 2*pi*r
where r = radius of circle,pi = 22/7 = 3.14
C = 2*pi*(80)
C= 160 (3.14) ft = 502.4 ft
